A/C problem in 1990 Civic

Can somebody help me? My a/c went out. I heard a loud squealing noise when it was on and when I turned it off, the noise went away. It was not what I expected being the fan belt making all the noise, but it was something else. Well now it doesn't make the noise, but also the a/c doesn't work. I have been told that it is the a/c blower motor, but I have also been told it needs refridgerant. If you can help, I would really appreciate it. Thanks, Ty

ur compressor prolly went.
